Yup, olive oil. It’s all the talk these days at cutting-edge cocktail bars around the country. It’s sweet without being sugary, and mildly earthy. Most importantly, it creates a silky cocktail unlike any you’ve tried before. Various ways of getting olive oil (or any other oil, for that matter) into your booze include “fat washing” your spirits, rinsing the inside of your glass with oil, or, like in this recipe for a drink I’ve called Popeye’s Girl (get it? Olive Oyl?), mixing the oil directly into the drink itself.
